Description

Technical Field

[0001] This invention relates to a switch, and more particularly to a touch switch. Background Technology

[0002] Rocker switches are widely used in wall switch panels in homes, offices, and industrial settings to control the on / off state of circuits for lights, sockets, and various electrical appliances. A typical structure includes a cover plate that swings around a central pivot, with the on and off ends respectively. During use, the user presses one protruding end of the cover plate with their finger, causing it to rotate around the pivot, lifting the other end and thus actuating the internal contact mechanism to switch the circuit state. This pressing operation is intuitive and provides clear feedback; users only need a single touch to turn the light on or off, leading to a stable usage habit.

[0003] Conventional rocker switches typically have a cover plate that curves upwards at one end, protruding noticeably from the mounting frame and disrupting the flatness and overall aesthetics of the wall. To improve appearance, the industry has introduced switches with covers flush with the frame, but these still retain the rocker-style triggering logic, where each end of the cover corresponds to the on / off function. In actual use, because the cover no longer has a noticeable protrusion, users often instinctively press the middle of the cover before developing a habit. However, pressing the middle does not cause the cover to swing, resulting in the switch not operating. Users need to consciously search for both ends, increasing the difficulty of use and contradicting their intuitive operating habits. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a touch switch that enhances operational intuitiveness while maintaining panel flatness.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A light-touch switch includes a mounting frame. An on / off module is disposed inside the mounting frame on one side embedded in a wall. Several cover plates are disposed on the side of the mounting frame not embedded in the wall. A trigger module is disposed between the cover plates and the on / off module. The cover plates are movable relative to the mounting frame toward the on / off module, and this movement includes a swing of one end of the cover plate perpendicular to the distribution direction of the several cover plates relative to the other end, and a translation of the cover plate toward the trigger module. During the above movement, the cover plate triggers the on / off module by pressing with a transmitted torque through the trigger module. After being triggered by the trigger module, the on / off module realizes the on or off of current.

[0006] The beneficial effects of this invention are as follows: This solution solves the problem of existing flush-mounted switches failing to trigger due to users habitually pressing the center by redefining the kinematic logic of the cover plate. The cover plate is configured to both translate as a whole and swing relative to the center, meaning that regardless of whether the user applies force to the edge or center of the cover plate, the force can be converted into effective displacement input. As a preferred embodiment, the back of the cover plate can be provided with a first abutment point distributed in the center area and a second abutment point distributed in the edge area. Both the first and second abutment points extend towards the trigger module and are located on the same arc surface. The center of this arc surface coincides with the rotation center of the cover plate, so that when the cover plate translates as a whole, the first abutment point linearly propels the trigger module, and when the cover plate swings, the second abutment point slides along the arc surface to propel the trigger module. Both translational and swinging movements can achieve press triggering through a unified torque transmission path. This composite motion mode transforms the user's random pressing pressure into a uniform trigger torque, eliminating the need to deliberately find a specific pressing position. The operation process aligns with intuitive cognition, reducing the learning cost. At the same time, the outer surface of the cover plate can still maintain a flush design with the frame, ensuring the overall simplicity of the switch panel.

[0007] Furthermore, the triggering module includes a swing rod. During its movement, the cover plate drives the swing rod to trigger the on / off module. The swing rod includes a rotating end, a bearing end, and a triggering end. The bearing end cooperates with the cover plate to drive the swing rod to rotate around the rotating end. During the rotation, the triggering end triggers the on / off module. The distance between the rotating end and the triggering end is greater than the distance between the bearing end and the rotating end.

[0008] By configuring the trigger module as a torque transmission structure including a swing arm, and converting the displacement of the cover plate into lever motion of the swing arm around the rotating end, the small pressing displacement on the cover plate can be effectively amplified into a sufficient actuation stroke of the trigger end, thereby reliably driving the on / off module. Specifically, setting the distance from the rotating end to the trigger end to be greater than the distance from the bearing end to the rotating end creates a force-multiplying lever relationship, which shortens the required pressing stroke on one side of the cover plate. As a preferred embodiment, the end face of the trigger end can be formed as an arc-shaped cam surface, with the radius of curvature of this cam surface gradually decreasing from the middle to both ends. This makes the contact point between the trigger end and the on / off module closer to the trigger center of the on / off module at the end of the swing arm's rotation stroke, increasing the pressing force component at the end of the stroke. This structure ensures reliable triggering within a limited space inside the switch, allowing the pressing surface of the cover plate to be made thinner and closer to the mounting frame surface, thus maintaining the slim and simple appearance of the product.

[0009] Furthermore, the cover plate is fastened onto the mounting frame in a direction perpendicular to its end face facing the mounting frame, and the cover plate moves up and down on both sides perpendicular to the distribution direction of the cover plate to release the connection between the cover plate and the mounting frame.

[0010] By using a vertical fastening method for the cover plate relative to the mounting frame, and setting the force required for disassembly to be applied along the vertical movement of the cover plate, a good balance between assembly stability and ease of disassembly is achieved. The vertical fastening direction is consistent with the movement direction of the cover plate when the switch is triggered, ensuring that the force generated during daily pressing operations will not be converted into a separation force that causes the cover plate to fall off, thus effectively preventing accidental loosening of the cover plate. As a preferred method, elastic locking arms that bend towards the mounting frame are formed at the upper and lower edges of the cover plate. The ends of the elastic locking arms have barbs that hook back towards the center of the cover plate. The mounting frame has corresponding limiting countersunk holes to accommodate the barbs. When the user inserts their fingernail or tool along the upper and lower edges of the cover plate and pushes the elastic locking arms outward, the barbs disengage laterally from the limiting countersunk holes, and the cover plate can be easily removed vertically. This connection method ensures a uniform gap between the cover plate and the frame while providing the user with a clear point of force for disassembly. Maintenance or replacement of a single cover plate can be completed without prying the entire panel, improving the convenience of product use and maintenance.

[0011] Furthermore, a positioning step is provided on the end face of the cover plate facing the mounting frame. The mounting frame includes two symmetrical horizontal and vertical frames, which surround and form a placement groove for inserting the switching module. An anti-detachment groove is provided on the horizontal frame corresponding to the positioning step. A locking rod is fixed in the anti-detachment groove. The positioning step and the locking rod cooperate to prevent the cover plate from detaching from the mounting frame in the direction away from the mounting frame.

[0012] By setting the engagement relationship between the positioning step and the locking rod to restrict only the unidirectional detachment movement of the cover plate away from the mounting frame, while allowing the cover plate to press and move towards the on / off module, the spatial independence of the fixing structure and the functional structure is clarified. The engagement interface between the positioning step and the locking rod is located in the horizontal frame area outside the placement slot, allowing the constraint point of the cover plate to shift from inside the frame to outside the frame. As a preferred embodiment, the locking rod can be constructed as a metal rod extending along the length of the horizontal frame, with both ends supported in the end support grooves of the anti-detachment slot. The positioning step has an arc-shaped guide portion and a right-angle stop portion on the side facing the locking rod. The arc-shaped guide portion guides the cover plate smoothly over the locking rod during vertical fastening, and the right-angle stop portion forms a surface contact lock with the locking rod after the cover plate is installed in place. This external constraint structure frees up space within the placement slot, allowing the installation width of the on / off module to be closer to the frame opening size, which is beneficial for increasing the internal wiring operation space or accommodating larger relay units, and improving the layout flexibility of internal components.

[0013] Furthermore, the locking rod cooperates with the outer wall of the anti-detachment groove to achieve locking between the locking rod and the anti-detachment groove. The positioning step is provided with a positioning protrusion facing the other positioning step. The anti-detachment groove is provided with an anti-detachment hole for it to enter and exit corresponding to the positioning step. The length of the anti-detachment hole along the direction perpendicular to the distribution direction of the cover plate is greater than the length of the positioning protrusion along that direction.

[0014] By utilizing the dimensional relationship that the length of the anti-detachment hole is greater than the length of the positioning protrusion, a clear travel space is provided for the lateral movement required for the cover plate to be disassembled. This makes the disassembly action specific: pushing the cover plate up and down along its distribution direction until the positioning protrusion moves to a position without interference within the anti-detachment hole. Only then can the cover plate be removed vertically. Thus, the anti-detachment and removable functions described above are achieved through a simple structure. As a preferred method, the positioning protrusion is a rectangular block structure with a lateral width that is one-half to two-thirds of the lateral length of the anti-detachment hole. The inner wall of the anti-detachment hole has a raised limiting rib on the side near the center of the cover plate. When the side of the positioning protrusion abuts against the limiting rib, the cover plate is in the normal working position. After the positioning protrusion slides past the limiting rib, the cover plate is in the vertically removable position. The limiting rib provides clear tactile feedback for the disassembly action. This structure ensures that when the cover plate is subjected to accidental pulling force in any direction under normal use, the positioning protrusion is blocked by the anti-detachment hole wall. It can only be unlocked by operating according to the preset lateral pushing path, effectively preventing the cover plate from falling off due to cleaning, wiping, or accidental scratches.

[0015] Furthermore, the trigger module includes a base, the interior of which is used to fix the on / off module. The swing rod is symmetrically connected to both ends of the base. One end of the swing rod is hinged to the base and the hinge position is the rotating end, and the other end is the trigger end. The load-bearing end is located between the rotating end and the trigger end. A suspension spring is provided between the cover plate and the swing rod. The two ends of the suspension spring abut against the cover plate and the swing rod respectively and are used to keep the cover plate suspended above the swing rod. The suspension spring is snapped onto the cover plate.

[0016] By integrating the on / off module and the swing rod onto the base to form the first assembly unit, and by engaging the floating spring with the cover plate to form the second assembly unit, and defining the cooperation relationship between each unit, the internal structure of the entire switch achieves modular and partitioned assembly. The floating spring provides elastic support between the cover plate and the swing rod, allowing the cover plate to maintain a suspended posture in a free state. When pressed, the cover plate overcomes the elastic force and moves downward, transmitting the motion to the swing rod. As a preferred embodiment, the base has hinged shaft seats at both ends, and the rotating end of the swing rod has an open-type claw structure. The swing rod directly engages with the hinged shaft seats through the claw structure to complete the hinged assembly. The side wall of the base has outwardly protruding buckles, and the mounting frame has corresponding slots on the placement groove wall. When the base, along with the assembled on / off module and the swing rod, is pressed into the placement groove from top to bottom, the buckles and slots engage and fix the switch. This modular assembly method allows the sub-assemblies of the base, switching module, swing rod, and cover plate and suspension spring to be pre-assembled outside the production line. Finally, only the two sub-assembly units need to be installed into the mounting frame in sequence, which significantly simplifies the final assembly process and facilitates rapid replacement during automated production and after-sales maintenance.

[0017] Furthermore, the suspended spring is provided with deformable arched feet at both ends perpendicular to the distribution direction of several cover plates. The mounting frame is provided with a deformation sliding groove for one end of the arched foot to slide within it. When the cover plate moves toward the switching module, the arched foot slides toward the end of the deformation sliding groove.

[0018] By setting arched feet at both ends of the suspended spring and cooperating with the deformation sliding groove on the mounting frame, the arched feet undergo forced deformation and end sliding within the sliding groove during the pressing of the cover plate. This deformation process continuously applies a gradually increasing downward pressure to the bearing end of the swing rod, which is transformed into a reliable and smooth rotational action of the swing rod. As a preferred embodiment, the bottom of the deformation sliding groove can be set as an inclined track that gradually rises from the starting end to the end. The end of the arched foot contacts the inclined track line. When the cover plate is pressed down, the arched foot climbs along the inclined track, forcing the arched foot to increase its own curvature and store elastic potential energy. This elastic potential energy simultaneously reacts to the cover plate, providing a rebound feel when pressing. The slope change rate of the inclined track can be designed to be steep at first and then gentle, making the initial pressing feel light and the final pressing feel clear. This structure converts the linear displacement of the cover plate into a continuous torque of the swing arm through elastic deformation, ensuring that the on / off module can obtain a stable and complete trigger input regardless of the pressing speed. At the same time, the deformation and sliding process of the arched foot itself constitutes the source of the operating feel, improving the user interaction experience.

[0019] Furthermore, the arched feet are symmetrically arranged at both ends of the suspended spring sheet perpendicular to the distribution direction of several cover plates. The deformation sliding grooves on both sides cooperate with the arched feet to achieve unidirectional limiting along the distribution direction of several cover plates, and the unidirectional limiting direction between the deformation sliding grooves on both sides and the arched feet is opposite.

[0020] By setting the limiting directions of the two arched feet in the distribution direction of the cover plate to be opposite to each other, a set of mutually antagonistic lateral constraints is essentially constructed on the suspended spring, effectively preventing the entire suspended spring and cover plate from deflecting due to uneven force during the sliding process. As a preferred method, a first shoulder is provided on the inner wall of the deformation sliding groove on one side. The outer side of the arched foot on this side is restricted by the first shoulder and prevented from shifting towards the first end of the cover plate. A second shoulder is provided on the outer wall of the deformation sliding groove on the other side. The inner side of the arched foot on the opposite side is restricted by the second shoulder and prevented from shifting towards the opposite direction of the first end of the cover plate. The two arched feet are mutually referenced and mutually restrain each other. This bidirectional interlocking limiting method ensures that no matter which side the user's pressing point is biased towards on the cover plate, the suspended spring can only deform and slide in the vertical direction, without torsion or lateral offset. This ensures that the torque borne by the bearing ends of the two swing rods remains balanced, ensuring the synchronicity and reliability of the on / off triggering at both ends, and avoiding uneven wear or malfunction of the contact points caused by mechanism sway.

[0021] Furthermore, the swing rod has a mating protrusion at its bearing end, the cover plate has a cross protrusion corresponding to the mating protrusion, and the suspension spring has a slot corresponding to the mating protrusion and the cross protrusion. At least one of the cross protrusions passes through the slot and abuts against the mating protrusion.

[0022] Through the cross-shaped protrusion, slot, and mating protrusion cross-positioning structure, precise point alignment and force transmission path are established between the cover plate and the swing rod while the suspended spring completes the snap-fit ​​fixation of the cover plate. The slot provides a positioning reference for the suspended spring, and at least one rib of the cross-shaped protrusion passes through the slot and directly abuts against the mating protrusion of the swing rod, accurately transmitting the movement of the cover plate to the swing rod. As a preferred embodiment, the cross-shaped protrusion consists of intersecting first and second ribs. The first rib extends along the distribution direction of the cover plate and is longer than the second rib. After passing through the slot, the two end faces of the first rib abut against the limiting surfaces on both sides of the mating protrusion, realizing gapless transmission between the cover plate and the swing rod in this direction. The lower end face of the second rib directly contacts the upper end face of the mating protrusion, forming a point-contact force transmission interface. This solution establishes a rigid force transmission link with no idle travel between the cover plate and the swing arm. Users can feel the clear resistance from the swing arm the moment they touch the cover plate, which improves the directness of operation. At the same time, the cooperation between the cross protrusion and the slot also enhances the installation rigidity of the suspension spring itself, preventing the spring from shifting position during long-term pressing.

Detailed Implementation

[0024] An embodiment of the present invention provides a light-touch switch, such as... Figure 1-9 As shown: The system includes a mounting frame 1. An on / off module 2 is installed inside the side of the mounting frame 1 that is embedded in the wall. Several cover plates 3 are installed on the side of the mounting frame 1 that is not embedded in the wall. A trigger module 4 is installed between the cover plates 3 and the on / off module 2. The cover plates 3 can move relative to the mounting frame 1 towards the on / off module 2. This movement includes the swinging of one end of the cover plate 3 perpendicular to the distribution direction of the several cover plates 3 relative to the other end, and the translation of the cover plate 3 as a whole towards the trigger module 4. This allows the on / off module 2 to be triggered by the trigger module 4 through a torque transmission when the user presses any area of ​​the cover plate 3, thereby achieving the on / off of current.

[0025] The mounting frame 1 includes two symmetrical horizontal and vertical frames, which together form a placement groove for inserting the switching module 2. A cover plate 3 is fastened to the mounting frame 1 along a direction perpendicular to its end face facing the mounting frame 1. The cover plate 3 can move vertically along the upper and lower sides perpendicular to the distribution direction of several cover plates 3 to release its connection with the mounting frame 1. A positioning step 31 is provided on the end face of the cover plate 3 facing the mounting frame 1. An anti-detachment groove 11 is provided on the horizontal frame of the mounting frame 1 at the position corresponding to the positioning step 31. A locking rod 12 is fixedly connected within the anti-detachment groove 11. The positioning step 31 cooperates with the locking rod 12, only preventing the cover plate 3 from detaching from the mounting frame 1 in a direction away from the mounting frame 1, without restricting the movement of the cover plate 3 towards the switching module 2. Compared to the existing technology where the cover plate is snapped onto the inner end face of the mounting frame, this embodiment places the mating position of the cover plate 3 and the mounting frame 1 outside the placement groove. This avoids occupying the internal space of the placement groove, facilitates the installation and subsequent maintenance of the switching module 2, and increases the mating contact area between the cover plate 3 and the mounting frame 1, effectively improving the stability of the cover plate 3 connection. The snap-fit ​​rod 12 is fixed by snapping into the outer wall of the anti-detachment groove 11. The positioning step 31 extends towards the other positioning step 31 and has a positioning protrusion 311. The anti-detachment groove 11 has an anti-detachment hole 111 at the position corresponding to the positioning step 31 for it to enter and exit. The length of the anti-detachment hole 111 along the direction perpendicular to the distribution of several cover plates 3 is greater than the length of the positioning protrusion 311 along that direction, so that the cover plate 3 can be disassembled and assembled with the mounting frame 1 by moving up and down. In addition, to facilitate the movement of the cover plate 3, a clearance groove is provided below the positioning step 31 to prevent interference when the positioning step 31 moves.

[0026] The trigger module 4 includes a base 42, the interior of which is used to fix and install the switching module 2. A swing rod 41 is symmetrically connected to both ends of the base 42. The swing rod 41 includes a rotating end 411, a bearing end 412, and a trigger end 413. The rotating end 411 is hinged to the base 42. The trigger end 413 is located at the end of the swing rod 41 furthest from the rotating end 411. The bearing end 412 is located between the rotating end 411 and the trigger end 413, and the distance between the rotating end 411 and the trigger end 413 is greater than the distance between the bearing end 412 and the rotating end 411. This makes the swing rod 41 a lever structure that requires more effort, effectively shortening the trigger stroke of the switching module 2 and ensuring a smaller movement distance of the cover plate 3, thus making the overall switch panel more concise and aesthetically pleasing. A suspension spring 44 is provided between the cover plate 3 and the swing rod 41. The suspension spring 44 is snapped and fixed on the cover plate 3, and its two ends abut against the load-bearing ends 412 of the cover plate 3 and the swing rod 41, respectively, to keep the cover plate 3 suspended above the swing rod 41.

[0027] The suspended spring piece 44 has elastically deformable arched feet 441 at both ends perpendicular to the distribution direction of the several cover plates 3. A deformation sliding groove 15 is provided on the mounting frame 1 at the position corresponding to the arched feet 441. One end of the arched foot 441 extends into the deformation sliding groove 15 and can slide along it. The deformation sliding grooves 15 on both sides cooperate with the corresponding arched feet 441 to achieve unidirectional limiting along the distribution direction of the several cover plates 3. The unidirectional limiting directions of the deformation sliding grooves 15 on both sides are opposite, effectively preventing the arched feet 441 from causing the suspended spring piece 44 to deflect during sliding, ensuring the stability of the swing rod 41 triggering. A mating protrusion 415 is provided at the load-bearing end 412 of the swing rod 41. A cross protrusion 32 is provided on the end face of the cover plate 3 facing the trigger module 4 at the position corresponding to the mating protrusion 415. A slot 442 is provided on the floating spring plate 44 at the position corresponding to the mating protrusion 415 and the cross protrusion 32. At least one of the cross protrusions 32 protrudes through the slot 442 and abuts against the mating protrusion 415, which further improves the mating stability between the cover plate 3 and the swing rod 41 and avoids deviation during force transmission.

[0028] The working principle of this embodiment is as follows: When the user presses any area of ​​the cover plate 3, the cover plate 3 will swing or translate in the corresponding direction according to the pressing position, and at the same time drive the suspended spring piece 44 attached to it to move synchronously. The arched feet 441 at both ends of the suspended spring piece 44 will slide along the deformation sliding groove 15 on the mounting frame 1 to the end of the groove. During this process, the suspended spring piece 44 undergoes elastic deformation and presses down on the bearing end 412 of the swing rod 41. After the bearing end 412 is subjected to pressure, it drives the swing rod 41 to rotate around the rotating end 411, so that the trigger end 413 at the other end of the swing rod 41 moves towards the pressing end of the on / off module 2 and presses the on / off module 2, thereby realizing the on or off of the current. Since the swing rod 41 adopts a force-consuming lever structure, a small displacement of the bearing end 412 can drive the trigger end 413 to complete a sufficient pressing stroke. Therefore, the overall movement distance of the cover plate 3 is greatly shortened, so that the switch panel maintains a flat and simple appearance. Meanwhile, since the swing rod 41 is symmetrically arranged at both ends of the base 42, and the suspended spring 44 can evenly transmit the pressing force from any position of the cover plate 3, the on / off module 2 can be stably triggered no matter which area of ​​the cover plate 3 the user presses.

[0029] The assembly process in this embodiment is divided into three independent assembly units, which are performed sequentially: First, the cover plate and the suspension spring unit are assembled, and the suspension spring 44 is snapped and fixed on the end face of the cover plate 3 facing the mounting frame 1, so that the cross protrusion 32 on the cover plate 3 passes through the slot 442 on the suspension spring 44; Second, the trigger module and the on / off module unit are assembled, and the on / off module 2 is fixedly installed inside the base 42, and then the rotating ends 411 of the two swing rods 41 are respectively hinged to the two ends of the base 42, so that the trigger ends 411 of the swing rods 41 are connected to the two ends of the base 42. 13. Align the pressing end of the on / off module 2; finally, perform overall assembly, snapping the trigger module and on / off module unit into the placement slot of the mounting frame 1, and then fastening the cover plate and the floating spring unit onto the mounting frame 1 in a direction perpendicular to the end face of the mounting frame 1, so that the positioning step 31 on the cover plate 3 passes through the anti-disengagement hole 111 on the anti-disengagement groove 11 and engages with the snap-fit ​​rod 12, while the arched feet 441 at both ends of the floating spring 44 extend into the corresponding deformation sliding groove 15, thus completing the assembly of the entire touch switch. During disassembly, simply move the cover plate 3 upward or downward along the distribution direction perpendicular to the cover plate 3. Taking the upward movement of the cover plate 3 as an example, the positioning protrusion 311 on the positioning step 31 disengages from the limit of the anti-disengagement hole 111, and the upper cover plate 3 is lifted up, so that the cover plate and the floating spring unit can be removed as a whole. The operation is simple and quick.
